Chris and I list postcards on and many times I can figure out the date of the issue by the cars, the buildings, etc. But there are a number of postcards we have that have the marquee (sp?)with an entertainer or two on them and I wonder if there is a way to find out when a certain entertainer performed at a certain casino! Any ideas? I know of a number of web sites with Nevada HXY but don't know if they have that sort of info, at least not the times I have looked! Like this button too, for instance!
